超极低体重儿,即出生体重不足1000克的小早产儿,其生存率虽在逐渐提高,但其合并症及长期预后却不能令人满意。如典型的合并症,新生儿慢性肺疾患,需要相当长时间的住院集中治疗,发生率在超极低体重儿中极高。根据最近调查,超极低体重儿因为慢性肺疾患,需要接受六个月以上集中治疗的病例,日本全国每年大约有150名左右。在超极低体重儿的远期后果中,最重要的是发生中枢神经系统严重后遗症,比例在10～15%,由于早产儿视网膜病所遗留的视力障碍病例也不在少数。在很多新生儿专科医院中,由于进行了超极低体重儿的连续观察,致使新生儿期的护理有了改善,但持续观察到学龄期的成果很少。超极低体重儿到了近四岁时,也可以应用田中比内式智能测验进行智商检查,到了学龄前,则可通过 WISC 智能检查,用智商(IQ)来进行智能发育的判定。在1～2岁时发现发育 Ultra-low birth weight children, that is, birth weight of less than 1000 grams of small premature children, although its survival rate gradually increased, but its complications and long-term prognosis is unsatisfactory. Such as the typical complications of neonatal chronic lung disease, require a long period of intensive hospital treatment, the incidence of ultra-low birth weight children extremely high. According to a recent survey, children with very low birth weight due to chronic lung disease need to be treated intensively for more than six months, with about 150 in Japan each year. In the long-term consequences of ultra-low birth weight children, the most important is the occurrence of serious sequelae of the central nervous system, the ratio of 10 to 15%, due to retinopathy of pre-term retinopathy left cases of visual impairment are also numerous. In many neonatology hospitals, care in the neonatal period has been improved due to continuous observation of ultra-low birth weight children, but there has been a continuous observation of very few school-age outcomes. Ultra-low birth weight children up to the age of four, you can also apply the Tanaka than the smart test for IQ test, to pre-school, you can by WISC smart check, IQ (IQ) for intelligent development of judgments. Found in 1 to 2 years of age
